the answer is 18

Step-by-step explanation:

3(x-2)=4

4+2=6

6x3=18

Kaley needs to score at least 830

Step-by-step explanation:

Normal Distribution

Assuming entrance exam scores are normally distributed, with a mean of and a standard deviation of , we can find the minimum score Kaley needs to be accepted at her college by using the z-score parameter defined as

We need to find X for a given value of z. Since the college demands an entrance exam score at least 2 standard deviations above the mean, X must be greater than , i.e.

Kaley needs to score at least 830
